As it is well known, at thepresent -tix-ne the edges of umbrella-covers,particularly that of ladies umbrellas, are frequently not: directlysecured to the ribs of the umbrellafbut are provided with tips which aresecured at the corners of the-umbrella cover segments and are fittedover the ends of the umbrella ribs, to retain the cover on -thes'ribs. II l It is the object of the Present invention to provide apparatus ofthe-character described which will enable one to secure :the attachmentnamed above to-the umbrella cover on the same sewing machine which washeretofore-used for sewing buttons thereon thereby makingpossible-greateconomyinplantequipment. I v I It is afurther;object1of;the present invention to devise apparatus c f thecharacter described which are particularly adaptable to be convenientlyand easily used for attaching the tips to v manner that will leave theedge of "the -cover smooth and continuous, and Will -eliminate thenecessit for :allowing an excess of material, as

Referring more specifically to the accompanying drawing, thegisewingmachine, which is .generally designated a's H0, is ;of the general typehaving a vibrating needle bar =l':l, iin which is arranged the needle12,.and which moves :the needle laterally and aransversely of themachine,

as well as reciprocating "it perpendicularly to they ever, that anyother machine having similar the samema'chine on whichthe buttons aresewn.

'This object is, 'broadly speaking,.1attained by-the provision of novelattachments for button'sewing machines by "means "er I which umbrella"cover tips may be accurately and conveniently held in position to bestitched *to the assoeiateef ra ri-p bythevibrat-irfgfiedleof'themachine."' I

characteristi'cs may be conveniently used.

The machine *fll fhas a work plateg-l 3in which -ther eis arranged theneedle plate l 3', having the needle islet" I 4 through which thevibrating needle l '2 is'reciprocated. :The machine is also provided"With'a spivoteddcar, for "lever 4 6, WhichY eXtends Ia'l'o'ng theworkiplate ll 3:andsisraisedthereabove, to the free end-of which buttonguides 'arenoranally Lattached. :In order to convert such machine l 0,f.or :the prur-posesof'thisinvention, there :is :secured near the freeend' of the lever it an :L-shaped bracket :l] ,o-ne arm l8 of which-issuppbrteilff romithe lever :l16 "and the other arm 18' at the end of thelever I6 and aipoint opposite the needle bar H and is provided withshoulders 29 and a threaded opening 2|. An arm 22 is arranged within thechannel [9 and is rigidly held therein by the shoulders 20 and by theset screw 23 passing through a slot 24 in the arm and engaging in thethreaded opening 2|. The arm 22 is arranged to extend forwardly, indirection of the needle and to one side thereof, and is provided with adownwardly offset end, at the extremity of which is carried an enlargedportion or head 25, which normally rests on the work plate 13. The head25 is provided with an aperture 26,

' is located, preferably, at a point intermediate When the ring 41 is tobe secured between two folds of material, instead of to a band, as

is the case when such ring is attached to a foldapparent that theapparatus described, consisting of the attachments shown and describedin association with a sewing machine of the character described, providemany advantages. Such apparatus enables the operator to perform theatprovided with the wing portions 3| to support the tip 29 in place. Themember 30 is so arranged that it will support the tip 29 in position tohave its eye 32 lie directly above the needle slot 14 at a pointapproximating. the position of the needle at one extreme of itsvibrating movement.

It will be readily seen that when. the tip 29 is arranged within theretaining means 30 the edge of an umbrella cover may be placed aroundthe rounded end of the tip, which'projects from the member 30, with theinner face of the cover 33 facing the tip, as is normally required to bedone when sewing one object or fabric to another on a sewing machine.The machine is then set into. operation and, as it will be obvious, theneedle I2 as it reciprocates and vibrates, will pass, alternately, oncethrough the! eye 32 of the tip 29 and the fabric surrounding it, andonce to the side of the tip, either through the fabric or alongside ofit, in a chain stitch formation. The cover will thus be secured to thetip by stitches extending only from the center of the tip to one sidethereof, to provide a smooth and continuous surface to the edge of theumbrella. cover, without any tucks or folds as heretoforeproduced inmachine attachment of the tips.

When the stitching. is completed, the tip 29 may be easily removed'fromits retaining means 30 and turned to face the inside of the cover 33,

and when in that position may be seated over the end of an umbrella rib,in a manner well known to those skilled in the art.

The arm i8 maybe provided with a groove 35 defining shoulders 36 andwith a threaded opening 3! and adapted to receive a second arm 38 insubstitution for the arm 22 when the latter is removed from its place.The arm 38 extends directly toward the needle 12 and is provided with adownwardly offset end, which normally rests on the needle plate 13' ofthe machine; the

said end being provided, preferably, with a forked extremit 39, passingabout the needle slot 44. Also provided on the end of the arm 38,directly to the rear of the needle slot 14, is an upright pin or post48, which is arranged in such position relative the needle [2 that whena button ring 4! is arranged about the post and held thereagainst, aportion of such ring 4| may be arranged over the needle slot M inposition to permit the vibrating needle to pass to either side of theportion of the ring lying over the needle slot, so as to stitch a fabricabout the ring, in a'manner which will be readily understood.

tachment of all accessories to an umbrella cover or case on the samesewing machine, and makes it possible to accomplish that with relativelysmall and simple alteration, by the relatively easy sub- 'stitution ofasingle, simple and readily accessible part of the machine. Theattachmentssubstituted are of simple construction and economical to makeand use.- They are easy to assemble and dismantle and require noparticular or new skill to operate.

What I-claim as my invention'is:
